You can batch up the commands for ICKDSF (the guts of CPFMTXA) to do multiple drives in series, but CMS is a single tasking OS. You can only do them serially, or you need to use multiple userids. (note that it doesn¹t have to be MAINT you can attach the disks to other userids from a privileged ID, and run CPFMTXA from any class G id).
You might be able to use CMSBATCH to speed things up, but it¹ll be tedious to set up.
